William Jackson Hooker
Sir William Jackson Hooker (6 July 178512 August 1865) was an English botanist and botanical illustrator, who became the first director of Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. Hooker was born and educated in Norwich. An inheritance gave him the means to travel and to devote himself to the study of natural history, particularly botany. He published his account of an expedition to Iceland in 1809, even though his notes and specimens were destroyed during his voyage home. He married Maria, the eldest daughter of the Norfolk banker Dawson Turner, in 1815, afterwards living in Halesworth for 11 years, where he established a herbarium that became renowned by botanists at the time. He held the post of Regius Professor of Botany at Glasgow University, where he worked with the botanist and lithographer Thomas Hopkirk and enjoyed the supportive friendshi ...

Icones Plantarum
''Icones Plantarum'' is an extensive series of published volumes of botanical illustration, initiated by Sir William Jackson Hooker. The Latin name of the work means "Illustrations of Plants". The illustrations are drawn from herbarium specimens of Hooker's herbarium, and subsequently the herbarium of Kew Gardens. Hooker was the author of the first ten volumes, produced 1837–1854. His son, Sir Joseph Dalton Hooker, was responsible for Volumes XI-XIX (most of Series III). Daniel Oliver was the editor of Volumes XX-XXIV. His successor was William Turner Thiselton-Dyer Sir William Turner Thiselton-Dyer (28 July 1843 – 23 December 1928) was a leading British botanist, and the third director of the Royal Botanic Gardens, Kew. Life and career Thiselton-Dyer was born in Westminster, London. He was a son of .... The series now comprises forty volumes.

Rosids Of Western Australia
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterolasia
''Asterolasia'' is a genus of seventeen species of erect or prostrate shrubs in the family Rutaceae, and is endemic to Australia.

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

York, Western Australia
York is the oldest inland town in Western Australia, situated on the Avon River, east of Perth in the Wheatbelt, on Ballardong Nyoongar land,King, A and Parker, E: York, Western Australia's first inland town, Parker Print, 2003 p.3. and is the seat of the Shire of York. The name of the region was suggested by JS Clarkson during an expedition in October 1830 because of its similarity to his own county in England, Yorkshire.John E Deacon: A Survey of the Historical Development of the Avon Valley with Particular Reference to York, Western Australia During the Years 1830-1850, UWA, 1948. After thousands of years of occupation by Ballardong Nyoongar people, the area was first settled by Europeans in 1831, two years after Perth was settled in 1829. A town was established in 1835 with the release of town allotments and the first buildings were erected in 1836.

Toodyay, Western Australia
Toodyay (, nys, Duidgee), known as Newcastle between 1860 and 1910, is a town on the Avon River in the Wheatbelt region of Western Australia, north-east of Perth. The first European settlement occurred in the area in 1836. After flooding in the 1850s, the townsite was moved to its current location in the 1860s. It is connected by railway and road to Perth. During the 1860s, it was home to bushranger Moondyne Joe. History Origin of the name 'Toodyay' The meaning of the name is uncertain, although it is probably indigenous Noongar in origin. In an 1834 reference it is transcribed as "Toodye" while maps in 1836 referred to "Duidgee" The Shire of Toodyay's official website says that " e name Toodyay is believed to be derived from an Aboriginal word 'Duidgee' which means 'place of plenty', referring to the richness and fertility of the area and the reliability of the Avon River". This meaning appears to be a long-standing belief in the local community, but may be based on an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Australiensis
''Flora Australiensis: a description of the plants of the Australian Territory'', more commonly referred to as ''Flora Australiensis'', and also known by its standard abbreviation ''Fl. Austral.'', is a seven-volume flora of Australia published between 1863 and 1878 by George Bentham, with the assistance of Ferdinand von Mueller. It was one of the famous Kew series of colonial floras, and the first flora of any large continental area that had ever been finished. In total the flora included descriptions of 8125 species.Orchard, A. E. 1999. Introduction. In A. E. Orchard, ed. ''Flora of Australia - Volume 1'', 2nd edition pp 1-9.

George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884.

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...
